BUSHING FOR BUNG-HOLES AND BUNG FOR USE THEREWlTH.

SPECIFICATION forming part of Letters Patent No. 291,194, dated January 1, 1884.

' Application filed April 23, 1853. (X0 model.)

To all whom it may concern:

Be it known that I, SAMUEL H. JENKINS, of the city, county, and State of New York, have invented certain new and useful Improvements in Bushing for Bung-Holes and Bungs for Use Therewith, of which the following isa full, clear, and exact description, reference being had to the accompanying drawings, and to the letlers of reference marked thereon.

My invention relates, especially, to metallic bushing for the bung-holes of beer-barrels and and has for its object the production of a bushstruct, easy to insert, and which will not break or become injured either while being inserted into the barrel or while in use.

A further object, of my invention is to pro vide a simple wooden bung which will always be effective in operation. I

To attain these desired ends my improved bushing consists, essentially, of a thimble of east or malleable iron. the periphery whereof is screw-threaded to engage with the edges of the hole prepared for its reception in the head or stave of a barrel. The outer wall of the bushing is vertical, and has a beveled shoulder at its outer extremity to regulate the depth to which it will enter the hole. The interior surface of the bush is tapering, in order to more readily engage with the bung when in-- serted therein, rendering the same secure against displacement. At the narrow end of the opening through the bushone or more shoulders are located, adapted and arranged to form a secure bearing for the wrench employed for inserting the same in the barrel. The bearing-faces of said shoulders-are radially situated to the body or. inner surface of the bush, and are fornfed upon an eccentric enlargement of the metal thereof. By such a construction and arrangement there is no undue strain upon the bush while being sunk' into place, and it may be constructed at less expense than has heretofore been necessary.

A bush-wrench having a stemprovided with eccentric projections conforming to the interior of the bush is employed for screwing the same into the aperture in the barrel, said wrench being the subject of a separate application for Letters Patent.

My improved bung is constructed of wood,

and is cut or bored partially through the cen- I ter, leaving a cap upon the smaller end, that extremity of the bung being beveled at an angle of about forty-five degrees, passing from the face to about the same plane as the bottom of the boring in the wood. This bung isintended for inserting in a metallic bushing, such as I have above described.

As heretofore constructed bungs have been made with a hole partially through their een' ter, but the bevel upon the inner end was not employed. Consequently when the faucet was driven into the center of such hung, with the intention of splitting off the cap-piece within the barrel, unless the grain of the wood of which such bung was formed ran horizontally and uniformly across the bung, it was liable to split diagonally, making an opening at the side of the faucet, through which the beer or other contents of the barrel escaped, causing much loss. By my peculiar method of construction this difiiculty is obviated, as, while not lessening the capacity of the cap-piece to resist .internal pressure, the point of splitting off, no matter how curled or oblique the grain of the wood of which the, bung be formed, must be at the bottom of the central boring,

and will not go above the bevel upon the ex- In the drawings, Figure 1 is a vertical cen-- tral sectional view of my improved bush, and

ity of the thread. The perforation through the center is tapering, while the exterior of the bush is vertical.

D are the shoulders formed at the smaller end of the perforation through the bush. Said shoulders may project one thirty-second of an In the drawings two shoulders D are shown; but one or more than two might be employed without departin from the spirit of my invention.

J is a wooden bung, cut or bored partially through the center K, as shown. A bevel, L, is formed upon the exterior of the bung at its smaller extremity, said bevel being at; an angle of about forty-tive degrees and cxtendingfrom the inner face of the bung to about the plane of the bottom of the perforation K, where a circumferential cut, Z, is formed around the periphery of the bung.

Having; now fully described my invention, whatI claim as new therein, and desire to secure by Letters Patent, is V 1. Ainetallic bung-hole bush, the outer wall whereof is vertical, screw-threzuled. and provided with a beveled shoulder, as set forth, and a tapering perforation passing through the bush, one or more inwardly-plotecting shouldersbeingloeated at orneartheslnallextremity of said perforation, the face ot'said shoulder or shoulders being radial to the body of the bush, and the inner surface of the bush eccentric in form, substantially as and for' the uses and purposes shown and described.

l l i t t i l I l l l l i t 2. The combination, with a bung-bush having body A, vertical exterior screw-thread, B, and beveled flange O, of inwardly-projeeting shoulders 1), the bearing-faces of said shoulders being radial to the body of the bush and the inner surface of the metal eccentric in form where said shoulders are located, substantially as shown and described.

8. A wooden bung partially bored through its center, as set forth, and provided with a detachable cap-piece formed by a circumferential cut around the periphery of the bung near its smaller extremity, substantially as and for the uses and purposes shown and described.

t. A wooden bung having a hole partially cut or bored through its center, as set forth,

and a bevel upon its smaller extremity, sub- &

stantially as and for the uses and purposes shown and described.

5. Bung J, the center whereof is cut away at K, the extremity of the bung being beveled at L, and provided with av circumferential out, I, forming a cap-piece, substantially as and for the uses and purposes shown and described.

In testimony that 1 claim the foregoing" I have hereunto set my hand in the presence of two witnesses.
